Monday, August 11, 2008This week we're publishing several blog posts dedicated to helping you with one response code: 404. Response codes are a numeric status (like 200 for "OK", 301 for "Moved Permanently") that a webserver returns in response to a request for a URL. The 404 response code should be returned for a file "Not Found". When a user sends a request for your webpage, your webserver looks for the corresponding file for the URL. If a file exists, your webserver likely responds with a 200 response code along with a message (often the content of the page, such as the HTML).
It's 404 week at Webmaster Central
